Geochronology, geochemistry and Sr-Nd, Hf-O isotope systematics of the Linte massif, Adamawa - Yade domain, Cameroon: Implications on the evolution of the Central African Fold Belt

•The Linte massif reveals a protracted magmatism which lasted at least 60 Ma.•Rocks show geochemical affinities of I-type, shoshonitic and metaluminous granitoids.•The 660 and 630 Ma rocks originate from source involving mantle material which could have been mingled or mixed with crustal component while the 600 Ma rocks come from crustal material.•They were formed during the syn- collisional phase of the Pan-African orogeny.
